The Oakley Gascan sunglasses are constructed with unique lenses that are cut from the curve of a single lens shield and mounted in the frame to maintain the original, continuous contour. The lens is polarized to filter out 99% of reflected glare while the Plutonite technology provides UV protection against harmful sunrays and blue light. High Definition Optics provides superior optical clarity and razor-sharp vision at every angle. The comfortable, lightweight O Matter frame offers durability and the three-point fit retains the lenses in precise optical alignment, eliminating pressure points common with frames that hook the ears.
